Summary: Epiretinal membrane formation in the macular area not infrequently occurs in the population over 50 years of age. The membranes develop as a result of proliferation of cells and deposition of collagen on the retinal surface. The exact cellular origin of the epiretinal tissue is not exactly established. In the initial stage, the ophtalmoscopic appearance is characterized by a mild sheen and hyperreflectivity in the macular area, called ?cellophane maculopathy?. In more advanced stages, increased tortuosity of the temporal arcade vessels can be observed, as well as striae and folds in the underlying neural retina. Prolonged traction from the epiretinal membranes can induce macular edema, macular cyst formation, and even small hemorrhages. When epiretinal membranes cause significant visual loss, surgical removal is considered.

Keywords: epiretinal membranes, posterior vitreous detachment, macular dysfunction, fluorescein angiography, pars plana vitrectomy, epiretinal membrane stripping.
